Piero della Francesca is one of the most famous painters of the XV century. He is considered as a mathematician devoted to paintings for his strict realistic study of space, obtained thanks to an application almost scientific of the perspective. The subjects of his works are often the occasion for the conceptual construction of a relationship “space-time” seen in an eternal moment where in fact the scene takes place. Developing the continuous possibility of mathematical researches of space, he extends the extremes of the scales of values almost in an unlimited way: towards the infinitely big and towards the infinitely small. The environment, the subjects, the images are concepts which get stronger one thanks to the other in a global context: anyway each of them keeps a reciprocal global independence.

There is a phenomenon of the quantum physics called “Entanglement”, name used to describe a non-local connection of two particles. Scientists have always thought that the universe worked according to the principle of locality (that is each interaction among particles should be “direct”) . According to this model a particle is moved or changed thanks to the physical interaction with another particle or with a chain of interaction of other particles. (Everything in the limits imposed by the Theory of Relativity which doesn’t allow speeds of interaction superior to that of light). Instead the phenomenon of the “Entanglement” is not local. Even if two particles are separated by such long distances and they cannot interact, they can reciprocally influence one on the other and, even more incredibly, at the same moment. For example if two photons are generated by an atom in this particular state of Entanglement and they go away one from the other in opposite directions, the Theory of Relativity states that they can no longer interact because they go away one from the other twice as much as the speed of light. Moreover, the state of polarization is indefinite for both of them (being in a state of quantum superimposition). It has been experimentally proved that the measuring of the polarization of one of the two photons compels the other to have an opposite polarization to the one measured, even if no communication is apparently possible. Such an interaction is instantaneous at infinite speed. In fact each observer sees a photon with a polarization that changes in a casual way each time. (If we know that the other observer is watching a photon with opposite polarization, this is absolutely useless for a system of communication).

The idea is that under certain circumstances two particles still form an only system, even if separated by enormous distances. The “non-locality” is a way to describe the situation, but it doesn’t give a physical explanation, a mystery still unsolved.

In a mathematical-perspective space of Piero della Francesca, reproduced according to the fresco of the “Flagellazione di Cristo” (The Flagellation of Christ), there are two female figures, without any shadows, bodies living in an almost unreal context. Actually they are “entangled” like the particles studied in the quantum mechanics. One turns her back on the other. If they are seen separately, they don’t seem to be aware one of the other, but in a context of “non-causality” they both behave the same way. The gesture made by the figure in the foreground (putting on her glove) is to be fulfilled also by the second one. The knowledge of an unreal space, perfectly balanced, ancient and humanistic, takes to starry universes, where the infinitely big is the frame and union (at the same time) of new border theories of the infinitely small… an “entangled” universe, which starting from aesthetic heritages distant in time, comes up again with scientific challenges (new and enigmatic), perfectly melted in the new will to know.
